My Inner Fish A Journey Into The 3.5 Billion Year History

Neil Shubin, author of â€Å"Your Inner Fish: A Journey into the 3.5-Billion Year History of the Human Body† once said, â€Å"in a perfectly designed world-one with not history-we would not have to suffer everything from hemorrhoids to cancer† (Shubin 185). In his account as a paleontologist, Shubin constructs a composition about our body’s history using fossils and DNA to compare the physical description of our body to that of the common fish. Upon reading his detailed scientific accounts, I can easily identify with a relation between his episodes and concepts from the general biology laboratory. Even though I was able to identify connections with course ideas and biological concepts throughout the book, I was immediately pulled to: â€Å"Handy Genes,† â€Å"The Best-Laid (Body) Plans,† and â€Å"Making Scents.† Among the episodes, the first that grabbed my attention was â€Å"Handy Genes.† Throughout the chapter, the reader is informed of the developmental composition of the human body. Shubin mentions that, â€Å"[†¦.] genetic switches help to assemble us. At conception, we start a single cell that contains all the DNA needed to build our body† (Shubin 46). The â€Å"making hands† section describes the orientation of the hands. This section points out that our limbs are created in three dimensions. These dimensions consist of a top and a bottom, a pinky and a thumb side, and lastly a base and a tip. With this, the author identifies differences from the bones at our fingers to our pinky shapes and side-to-sideShow MoreRelatedEssay about Your Inner Fish1511 Words   |  7 PagesKalia Espinoza Macdonald AP Biology 30 August 2010 Your Inner Fish Your Inner Fish, by Neil Shubin, is a journey into the 3.5- billion- year history of the human body.

Adolescent Years - 1927 Words

Adolescent Years Paper Adolescence is the developmental stage between childhood and adulthood; it generally refers to a period ranging from age 11 and 19. Adolescence has many psychological and social stages, as well as biological. The beginning of adolescence is usually marked with the beginning of puberty. Adolescence can be prolonged, brief, or practically nonexistent, depending on the type of culture in which it occurs. Adolescence is somewhere between childhood and adulthood. It is filled with constant change, uncertainty, but it can be wonderful and full of expectation. Everything a child learned to believe is suddenly challenged. One day you are a cute child that everybody seemed to adore, and the next day your skin and body are†¦show more content†¦This image may be thin, muscular, or just average. During adolescence, they may feel unsatisfied with their bodies and want to change how they look just to fit in. This gives adolescence a feeling that they belong, and pee r influences help the adolescence grow as an individual, by getting insight and advice from those who know. During this time, adolescents are going to start looking up to a number of people, namely celebrities, and try to adopt their style as their own in hopes of being able to fit in (Cheathouse, Sept., 2004). Adolescent girls need someone to look up to, and if they look up to celebrities and want to be like them, they may do anything to achieve the same look (Botta, 1999). Besides the idea of finding ones identity and fitting in, many of these conflicts lead to inappropriate behavior such as sneaking out, drinking, drugs, pre-marital sex, and the worst one of all, pregnancy (Bruin).

We will write a custom essay sample on William Golding – Lord of the Flies or any similar topic only for you Order Now These world wars shaped the way he viewed the world, especially WWII as he was part of the destruction of German ships on D-Day. These experiences were a big reason why Golding chose to become an author. Golding wrote many books but one book really showcased his thoughts and feelings about humans and how cruel they truly can be. This book is of course is Lord of the Flies, which was published in 1954 at a time where the world feared of a nuclear war. For those of you who don’t know the book, Lord of the Flies is a book about a group of young schoolboys, who are stuck on an island and in a time of chaos and fear, turn to savagery, resulting in horrific actions and behaviours. These behaviours and actions are written with such detail that it makes the action even more horrific. For example in chapter 11 one of the boys, Roger, pushes a boulder off the edge which results in the death of one of the boys, Piggy, it reads, â€Å"His head opened and stuff came out and turned red. Piggy’s arms and legs twitched a bit, like a pig’s after it has been killed. † Golding says in an article, ‘What turns children into savages’ that he includes descriptions like these to get the reader thinking about how cruel humans can really act towards one another and how it can hurt innocent people.

The Last Duel by Eric Jager free essay sample

This story is placed in France in 1386. This story speaks of how cruel this time was. It also states how serious crime accusations were taken. This duel is about an offence committed eleven earlier months. The duel is to be between two men who were once friends. The men are to duel each other because Lady Marguerite is not allowed to directly accuse LeGris herself of this crime, because she is women. In the time period the story is based in, women have very few rights. Lady Marguerite looked to her husband for help. She asked him to accuse LeGris of raping her while he was away on business in Paris. Her husband becomes her champion to fight on her behalf. Lady, being a woman, is considered his property this makes the crime against him. Marguerite endured pregnancy leading up to the duel. Jager makes sure to show us how hard it was for Lady Marguerite to speak up about the attack. We will write a custom essay sample on The Last Duel by Eric Jager or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page I think Eric Jager is a phenomenal writer. His writing is powerful and descriptive. His battle scenes describe how detrimental the duel is for the two noblemen. This is also important for Lady Marguerite de Carrouges, who would be burned to death if her husband is to lose. This story is presented in two main parts, both enclosing chapters. This is written in an organized fashion. First, the prologue speaks of the conflict, the duel the two men are having. Then, Jager takes us back to tell us what has happened in the past leading up to the time of the duel. This story seems to present new information; it does not show that he is just re-writing what others have already written. The book fulfills its purpose to explain how the justice system worked and how cruel people used to be. He has succeeded at thus; he displays information well and has created a great historical plot to show what the book is meant to do. This book is a good historical book and I do recommend it to those who enjoy history. Eric Jager is a good author, he specializes in medieval literature. I recommend reading his other books if you enjoyed this one. He has also written â€Å"The Book of the Heart†, and â€Å"The Tempters Voice†. This are his older stories compared to â€Å"The Last Duel† witch is one of his newest. I was not a huge fan of this book. It is very well written, but I do not usually like historical books. I do give Jager credit because it is the best historical book I have ever read. It is well put together and full of information on the topic. I did not find the subject interesting so I did cloud my view of the story some-what. This story is good for its intentions, to write about true events in medieval history.

Urinary system essays

Urinary system essays The urinary system removes wastes from the blood and forms it into urine. The urine produced usually contains excess water, ions, urea and other toxic substances. The urine created by the kidneys is moved through the ureters and is stored in the bladder until it is released through the urethra. The nephron is the functional unit of the kidney. It consists of a renal corpuscle, a proximal tubule, a loop of Henle, and a distal tubule. The renal corpuscle is made up of Bowmans capsule and the glomerulus. The Bowmans capsule surrounds the glomerulus, which are capillaries that are packed together to form a ball-like structure. The Bowmans capsule consists of podocytes, an epithelial cell, that attaches to the outer surface of the glomerular capillary. The glomerular capillaries and the podocytes form the filtration membrane. The descending limb is made up of a thin wall of simple squamous epithelium. The rest of the nephron consists of simple cuboidal epithelium, along with mi crovilli and many mitochondria. There are three processes that are critical for urine production which are filtration, reabsorption and secretion. Filtration is the movement of water and small molecules through the filtration membrane of the renal corpuscle. The portion entering the nephron is called the filtrate. The formation of filtrate depends highly on filtration pressure. The pressure in the nephron is higher than in any other capillary. This is due to the juxtaglomerular apparatus which releases renin. Renin causes the constriction of smooth muscle around the capillary producing an increase in pressure. The blood pressure is usually between 45-50 mmHg. Colloidal osmotic pressure moves water back through the filtration membrane. It is about 28 mmHg. Hydrostatic pressure also works against the high pressure coming in. It is the pressure of fluid in an enclosed space and it is 10 mmHg. Therefore the net filtration ...

Systems Requirements Engineering Essay Example | Topics and Well Written Essays - 1500 words

Systems Requirements Engineering - Essay Example It is the phase that encompasses those tasks that go into determining the needs to meet the goals, taking account of the possible conflicts and specifying the overall risks. A sub-phase of the requirements specifications which deems high importance is Software Requirements Specification (SRS). SRS is a description of a behavioral aspects of the system which includes all the interactions that the users will have with the product (Stellman & Greene, 2005). Modeling is a central part of all activities that lead up to the deployment of a good software (Booch et al, 2005). Modeling is exactly the role that Unified Modeling Language plays in requirements specifications. The role of Unified Modeling Language is to model interactive systems, whose behaviors emerge from the interaction of their components with each other and with the environment (Goldin et al., 2001). In traditional computation, algorithmic models were sufficient for description of requirements. However, todays interactive systems which are capable of self reconfiguring and adapting to their environment, algorithm tools do not suffice. Unlike traditional procedural languages, UML provides support for the inherently open-ended preliminary steps of systems analysis and specification, which are becoming increasingly complex (Wegner, 1997). UML is used to visualize, specify, construct and document the artifacts of the software-intensive system. A software of any nature or propor tion will have multiple methods, functions, interface and external and internal accesses. To support such a broad mix of entities, UML provides different views to analyze this software. Analysis of each of this views gives the software designer a set of requirements which can be consequently forward engineered. The prominent views provided by UML are Use Case View, Component View, Deployment View, Concurrency View and Logical View (Eriksson & Penker, 1998). Use Case View: Requirements capture has two objectives: to find the true requirements and to represent them n a suitable way for the users, customers and developers (Jacobson et al., 1999). True requirements are the end user functionalities desired by the user of the system. These functionalities must be presented in a way such that users spend minimum amount of time understanding it. Use Cases can be applied to capture the intended behavior of the system being developed, without having to specify how that behavior is implemented (Booch et al., 2005). UML provides Use Case diagrams to model the Use Case View. Logical View: The purpose of logical view is to specify the functional requirements of the system. This means that the logical view shows both the static and dynamic views of the system. The logical view concentrates on getting the best logical grouping of functionality into objects (fincher, 2007). The main artifact of logical view is the design model which gives a concrete description of the functional behavior of the system. UML provides Class diagrams and Object diagrams to model

Why the Labout Party Took Long to Make Itself Electable after 1979 Essay

Why the Labout Party Took Long to Make Itself Electable after 1979 - Essay Example The Labour party was founded on democratic socialism. As a result, it had close affiliations with trade unions (Lyman 1957). As a matter of fact, the party was founded so as to fight for the rights of the workers. The party rose from its humble beginnings in 1990 to form its first government under Prime Minister Clement Attlee. Labour party was in office from 1945-1951. This government was the most radical of all British governments to have come into office in the 20th Century. It strived to implement the theories espoused by John Maynard Keynes, among others. This government nationalized key industries where it had majority stake. An example of such industries was banking; where the bank of England was taken back by the government. The same case happened with mining, telecommunications and transport, steel, railway and canals industries. They believed the government had to have a hand in the running of vital industries, an idea that seems so out of place in the era of rapid privatiz ation (Lyman 1957). The Attlee government also instituted the N.H.S (National Health Service). This is a program of socialized medicine that is the envy of the world today. This scheme made affordable healthcare accessible to the extremely poor people in the society. The Attlee government was also behind the slow dismantling of the British Empire. Independence was granted to several colonies, most notably India, the jewel in Britain’s imperial crown. The party went on to lose the 1951 general election to the Conservatives, and spent several years in opposition until Labour’s Harold Wilson was elected Prime Minister in 1964. Harold Wilson’s administration also reinforced the idea of ‘labour’ as the true Leftist party by putting in place sweeping social and educational reforms. Key among them was the legalization of abortion and homosexuality. On the educational front, comprehensive education was made accessible to millions through the creation of the Open University. This is another idea that has been replicated by the rest of the world. Even with such positive changes, Labour party was voted out of office in 1970. The party had inherited a large trade deficit that triggered a currency crisis in which the pound was severely weakened. The party was to return to power again in 1976 under James Callaghan. This administration was tirelessly trying to battle the economic crisis present at that time. It ruled with a slight majority in the Commons. Internally, the party was split down the middle over Britain’s membership of the European Economic Community, E.E.C. The issue had to go to referendum. The public showed its overwhelming support for Britain’s continued membership with a two thirds majority. By this time, inflation stood at a staggering 23%. The government successfully lowered inflation by a policy of wage restraint to a rate of 7%. However, this brought cracks in the relationship between Labour and the trade u nions who wanted wages to move only in one direction, up. To shelter ordinary Britons from this economic storm, the Labour government presided an era of rising pensions coupled with massive subsidies on food items (Lyman 1957). This was aimed at to protecting the tiny incomes that had already been decimated by inflation in the rest of the economy. The government sauntered on and introduced several welfare schemes to protect the extremely poor. Pensions of the disabled were significantly increased, and employment legislation ensured that people could be hired even for a short time. Pregnant women were also granted leave. Workplace inspection was prioritized to prevent workers from hazardous working conditions. Unfair dismissal was also curbed through Industrial Tribunals. While the

Recalling the Holocaust - Essay Example The Nazis committed mass murder of the Jews in gas chambers. The use of gas chambers was one of the Nazi’s plans to eliminate all Jews from the German society. The killing of infants occurred before their birth. The gas chambers used carbon monoxide as the killer gas during the Holocaust. The use of carbon monoxide was an inhumane act. It allowed for the mass murder of the Jews by the Nazis. The first mass killing using gas chambers was in 1939. The killing that occurred at Owinksi hospital led to the death of over one thousand Jews including children. That the concentration camps, the use free standing chimneys to kill Jews presented one of the most atrocious acts. A high number of prisoners suffered their fatal fate because of the brutal killing using the freestanding chimneys in the camps. It remains one of the extreme violations of the rights of humanity. Phil Donahue’s interview is a revelation of the truth behind the inhumane acts that surrounded the Holocaust. It exposes the high number of Jews who suffered the atrocities experienced in the important event, that it, the Holocaust. The attempts by supporters of the Holocaust to deny the use of gas chambers to kill the Jews are unbelievable and tantamount to the denial of committing a crime. Dr. Franciszek is one of the most informed people on the holocaust incidence. Dr. Francisze's claims that the number of victims was less than that originally estimated seems ill-intentioned and driven by impunity....

Adsorption of Volatile Organic Compounds

Adsorption of Volatile Organic Compounds ADSORPTION OF VOLATILE ORGANIC COMPOUNDS ON DIFFERENT TIMBER SPECIES Marco Vasconcelos1, Nereida Cordeiro1,2* ABSTRACT Due to the health issues associated to VOC, this work aims to study the adsorption of these compounds onto timbers, in order to improve air quality. For this task, inverse gas chromatography (IGC) was used to characterize surface properties (surface energy, specific free energy and enthalpy of adsorption). Dispersive component of the surface energy (ÃŽ ³SD) ranged from 39.95 to 43.81 mJ/m2, corresponding to Amburana and Courbaril respectively. Yellow Pine shows higher values of the specific free energy of adsorption (à ¯Ã‚ Ã¢â‚¬Å¾G ºs), indicating a higher number/energy of polar active sites. On the other hand, the enthalpy of adsorption values (à ¢Ã‹â€ Ã¢â‚¬  Hs) don’t go in agreement with à ¯Ã‚ Ã¢â‚¬Å¾G ºs, probably due to its temperature-dependence. That said, the à ¢Ã‹â€ Ã¢â‚¬  Hs values indicate a basic surface and Amburana establishes stronger interactions with polar probes while Yellow Pine establishes stronger interactions with cyclohexane. Additionally, the â€Å"thermodynamic compensation effect† was evaluated on these samples, being observed linearity in Yellow Pine, Grapia and Brazilian Mahogany. The slope was similar between the different species, indicating a similar adsorption mechanism. Keywords: Inverse Gas Chromatography, Surface Properties, Wood Fibers, Volatile Organic Compounds, thermodynamic compensation effect 1. INTRODUCTION Volatile organic compounds (VOC) are organic compounds produced in industries, motor vehicles, power plants, etc. They are usually distinguished by boiling temperatures under 250 ºC, at standard atmospheric pressure (1 atm), and with high vapor pressures, surpassing 0.5 kPa at 25 ºC (Dobre, Pà ¢rvulescu, Iavorschi, Stroescu, Stoica, 2014). The aforementioned compounds have harmful impact on human health, such as eye and throat irritation, damage to the liver, central nervous system and carcinogenic effects, due to prolonged exposure (Das, Gaur, Verma, 2004). Therefore, reducing the VOC concentration on the atmosphere is an important task in order to improve air quality and avoid health issues. Wood fibers consist in both dead and living cells, being at a macroscopic level organized within a layer of xylene, in the wood. From the chemical point of view, consists mostly in cellulose, followed by hemicellulose and lignin. Due to the hydrogen bonds established by the hydroxyl groups of cellulose of the surface, it affects strongly on the properties of the material, such as hydrophobicity and therefore its reactivity (Hodzic, Shanks, 2014). About 80.5% of the wood fibers are used in the paper industry and around 17% for wood fibers modification (composites: Kazayawoko, Balatinecz, Romansky, 1997; Adusumali, Reifferscheid, Weber, Roeder, Sixta, Gindl, 2006; Cao, Hu, Liu, 2008). In this work, Inverse gas Chromatography (IGC) was used to characterize the surface properties (surface energy, specific free energy and enthalpy of adsorption) of Amburana, Yellow Pine, Grapia, Courbaril and Brazilian Mahogany to evaluate the adsorption of some VOC (Chloroform, cyclohexane, ethyl acetate, benzene and toluene). Additionally, the â€Å"thermodynamic compensation effect† was studied to investigate the mechanism of thermodynamic adsorption on the different samples analyzed. 2. MATERIALS AND METHODS 2.1 Materials Methane (>99.99% purity) was used an inert reference probe and the carrier gas utilized was helium (>99.99% purity), both supplied by Air Liquide Company. The probe molecules were supplied by Sigma–Aldrich with GC grade (>99% purity). 2.2 iGC analysis iGC measurements were carried out, at least, in duplicate, on a commercial inverse gas chromatograph (Surface Measurements Systems, London, UK) equipped with a flame ionization (FID), thermal conductivity (TCD) and mass spectrometer (MS) detectors. Standard glass silanized (dymethyldichlorosilane; Repelcote BDH, UK) columns with 0.4 cm ID and 30 cm in length were used. About 1.5 g of timber sawdust mesh 40-60 was packed by vertical tapping for 10 min. The columns, with the samples, were pre-treated for 2h at 343 K and 10 ml/min of flow rate, to remove the impurities adsorbed on the surface and 2h at the measurement conditions. After pre-treatment, pulse injections were carried out with a 0.25 à ¯Ã‚ Ã‚ ­l gas loop. The iGC system was fully automated with purpose written control software (SMS iGC Controller v1.3) and data were analyzed using iGC Standard v1.3 and Advanced Analysis Software v1.21. The presented results are the average of the values obtained for each sample with a standard deviation minor than 5%. Measurements of the dispersive interaction were made with n-alkanes (n-decane, n-nonane, n-octane, n-heptane and n-hexane) at 298 K, at 0% RH. The carrier gas (Helium) flow rate was 10 ml/min. To acid-base studies cyclohexane, benzene, chloroform, toluene and ethyl acetate were used at 0% RH. Heat of sorption measurements were done with the polar probes at 298 K, 0% RH, and 10 ml/min flow rate. 3. RESULTS AND DISCUSSION 3.1 Dispersive component of the surface tension The solvent–sorption properties of the timbers were studied at infinite dilution condition in order to remove the interactions between the probe molecules adsorbed at the surface of the samples. The methane injection allows the calculation of the dead time and subtracts it to the retention time in order to obtain the retention volume (Thielmann, 2004). The corrected net retention volume VN is given by: where Vd is the mobile phase hold-up volume (called dead volume), and VR the measured retention volume. The 0 superscript indicates a correction for the column pressure drop given by j: where where T is the column temperature, F is the exit flow rate at 1 atm and 273.15K, tR is the retention time and t0 is the mobile phase hold-up time. The dispersive component of the surface energy, as well as the specific free energy of sorption, was measured with dispersive and acid-base probe molecules. The relation between the retention volume and free energy of sorption à ¢Ã‹â€ Ã¢â‚¬  G ºS is given by the following equation: à ¢Ã‹â€ Ã¢â‚¬  G0S = RTln VR0 + K where R is the gas constant and K is the De Boer or Kemball/Rideal constant depending on the chosen reference state (De Boer, 1953; Kemball Rideal, 1946). Moreover, à ¢Ã‹â€ Ã¢â‚¬  G0S is related to the energy of adhesion WA (between probe molecule and solid) by the equation: à ¢Ã‹â€ Ã¢â‚¬  G0S = NAaWA where a is the cross sectional area of the adsorbate and NA the Avogadro constant. According to Fowkes (1964), the dispersive contribution of the work of adhesion WA is given by: WA = 2(ÃŽ ³SDÃŽ ³LD)1/2 with ÃŽ ³SD and ÃŽ ³LD as the surface tension of the adsorbent and the adsorbate respectively. Combining the equations above: Thus, the dispersive component of the surface tension (ÃŽ ³SD) values could be calculated based on the plots of RT lnV0R vs a(ÃŽ ³LD)1/2 for the adsorption of n-alkane probes, as illustrated in Figure 1. Good linear correlations (0.9991-0.9996) were obtained for the n-alkane series for all samples analyzed. The calculated ÃŽ ³SD values are given in Table 1 and show very similar results between the different timber species. The surface energy ranged from 39.95 to 43.81 mJ/m2, corresponding to Amburana and Courbaril respectively. These values are similar to those reported by Kazayawoko, Balatinecz, Romansky (1997) and Shu, Xu, JinWei, BaoLi (2007) for wood flour (35.6 mJ/m2 at 323K) and ashtree wood meal (36.52 mJ/ m2 at 323K) respectively. Gouveia, Cordeiro and John (2011) reported various lignocellulosic fibres (flax, hemp, kenaf, agave, agave hybrid pineapple, and sisal), with ÃŽ ³SD values ranged from 37.17 to 51.37 mJ/ m2 (at 298K). In the same article aforementioned, it’s also explained that variations in the ÃŽ ³SD values can be due to the different composition, growing conditions of the fibers and method of extraction. The latter is justified due to the fibers being usually covered by a layer of wax, and may interfere with elutant-fiber interactions. When removed during the method of extraction it’s expected to change drastically the surface energy. 3.2 Polar probes sorption studies A widespread approaching to the Lewis acid/base surface interactions can provide better perceptive of the chemical-physical properties of the timber surfaces. The presence of acid and base active sites on the surfaces increases the possibility of specific intermolecular interactions with solvents and others compounds. The specific free energy of sorption, à ¯Ã‚ Ã¢â‚¬Å¾G ºs was determined by the distance between the alkane line and the points corresponding to the ΔG ºs value of polar probes (Gamble, Leane, Olusanmi, Tobyn, Supuk, 2012). à ¯Ã‚ Ã¢â‚¬Å¾G ºs = RTln(VN) – RTln(VNref) The à ¯Ã‚ Ã¢â‚¬Å¾G ºs values are given in Table 2 and represented in Figure 2. Chloroform was used as an acid probe on this work. The values ranged from 0.53 to 2.50 kJ/mol, corresponding to Brazilian Mahogany and Yellow Pine respectively. Based on the results obtained, the à ¯Ã‚ Ã¢â‚¬Å¾G ºs values of Chloroform decrease in the following order Pine > Grapia > Courbaril > Amburana > Mahogany. This observation indicates that Yellow Pine may have a higher quantity/energy of active sites with basic character compared to the other fibers. A similar order was observed on Cyclohexane, indicating that Yellow Pine might also have a higher quantity/energy of active sites with apolar character. Although, the same order is not observed in ÃŽ ³SD, since that for the surface energy were used n-alkanes and due to the shape of cyclohexane and consequent different steric hindrance, it will have different interactions with the surface. On the other hand, Brazilian Mahogany shows the lowest à ¯Ã‚ Ã¢â‚¬Å¾G ºs values for the overall probes, indicating a lower quantity/energy of active sites. Ethyl acetate was used as a basic probe in Amburana, Yellow Pine and Courbaril. The interaction of this probe, alongside chloroform, with the timber surface indicates the presence of both acidic and basic sites on the solid surface. 3.3 Heat of sorption measurements In the infinite dilution region, where the isotherm is linear, VN should be measured at a range of column temperatures and ln(VN/T) plotted vs. 1/T, which yields the heat of sorption à ¢Ã‹â€ Ã¢â‚¬  Hs according to (Conder Young, 1979): To determine the enthalpies of sorption (à ¯Ã‚ Ã¢â‚¬Å¾HS) of the VOC’s in the timber species, the specific retention volume (VN) was measured at different temperatures (293 to 298K) and the retention diagrams ln VN vs 1/T were plotted (Fig. 3-7). Some of VOC ´s couldn’t be used in some of the timber species because the retention time was too low to make accurate calculations due to the peak overlap. The à ¢Ã‹â€ Ã¢â‚¬  Hs values are given in Table 3, determined at three different temperatures. Good linear correlations (>0.99) were obtained for the probes used, as shown in Figures 3-7. In this work, the à ¢Ã‹â€ Ã¢â‚¬  Hs values for the basic probes (Ethyl acetate; Higher DN/AN*) were lower than the à ¢Ã‹â€ Ã¢â‚¬  Hs values for the acid probes (Chloroform; Lower DN/AN*), indicating a basic character of the solid surface. Cordeiro, Mendonà §a, Pothan and Varma (2012) and Gouveia, Cordeiro and John (2011) observed the same basic character in macro and nanobanana fibers, flax, hemp, kenaf, agave, agave hybrid pineapple, and sisal. For chloroform, the à ¢Ã‹â€ Ã¢â‚¬  Hs values decreased in the following order: Amburana > Brazilian Mahogany > Grapia > Courbaril > Yellow Pine. At first sight it indicates that Amburana establishes stronger interactions with the surface, compared with the other timbers. On the other hand, Yellow Pine establishes the weakest interactions with chloroform. A similar order was also observed for cyclohexane, for the exception of Yellow Pine, that shows the highest à ¢Ã‹â€ Ã¢â‚¬  Hs value for this probe. The results don’t go in agreement with the ones obtained from the specific free energy of adsorption study, probably due to the fact that the temperature might influence the à ¯Ã‚ Ã¢â‚¬Å¾G ºs values and therefore it might mislead to incorrect conclusions. Thus, the à ¢Ã‹â€ Ã¢â‚¬  Hs values will give a better insight of which timber is advised (or not) to remove VOC from the atmosphere since it already have in account the temperature. Being said, the results indicate that for polar probes Amburana have stronger interactions while for apolar probes Yellow Pine have stronger interactions. 3.4 Entropy of Sorption calculation The linear dependence between ΔHS and ΔSS is called â€Å"Thermodynamic Compensation Effect†. Normally, stronger intermolecular interactions (related to ΔHS) result in less degrees of freedom of the elutant, leading into a greater order of the system, decreasing the entropy of the system (Liu L., Guo Q-X., 2001). The entropy of sorption was directly calculated according to: Figure 8 represents the entropy-enthalpy correlation, being only observed on Yellow Pine, Grapia and Brazilian Mahogany. All three dependences are linear and almost parallel, with a slope between 2.7910-3 and 3.7310-3 K-1. Therefore, these three samples follow the previous equation. According to Korolev A. et al., (2011), a similar slope indicates similar adsorption mechanism on the samples studied on this work. Since all the samples have similar composition, it was expected the same adsorption mechanism between them. 4. CONCLUSION IGC was used to evaluate different surface properties, namely surface energy, specific free energy and enthalpy of adsorption. The ÃŽ ³SD values were measured at 298K and ranged from 39.95 to 43.81 mJ/m2. These variations between results are due to different composition, growing conditions and method of extraction. The results don’t go in agreement between enthalpy of adsorption and the specific free energy of adsorption probably due to the influence of the temperature on the à ¯Ã‚ Ã¢â‚¬Å¾G ºs. In Yellow Pine were observed higher à ¯Ã‚ Ã¢â‚¬Å¾G ºs values for chloroform and cyclohexane compared to the other fibers, indicating a higher quantity/energy of active sites with basic and apolar character. In Amburana, Yellow Pine and Courbaril, the basic probes showed lower à ¢Ã‹â€ Ã¢â‚¬  Hs values compared to acid à ¢Ã‹â€ Ã¢â‚¬  Hs values, indicating a basic character. The same was observed on other fibers found in literature. Amburana establishes stronger interactions with Chloroform while Yellow Pine establishes stronger interaction with cyclohexane, compared to the other timber species. The â€Å"Thermodynamic Compensation Effect† was only observed in Yellow Pine, Grapia and Brazilian Mahogany, with linear fits almost parallel. The slope ranged between 2.7910-3 and 3.7310-3 K-1. Similar slopes indicate similar adsorption mechanism, which makes sense due to similar composition. ACKNOWLEDGEMENT References Adusumali R-B, Reifferscheid M, Weber H, Roeder T, Sixta H, Gindl W.

Filipino Children’s Uses of the Internet and Mobile Phone Essay

I. STATEMENT OF THE PROBLEM How do Filipino children integrate the Internet and mobile phone into their everyday life and peer and family relationships? This study is a response to a suggestion by Sonia Livingstone (2003) to investigate further children’s relationships in the new media environment. It also seeks to address the lack of empirical studies on Filipino children’s engagements with and in the new media, specifically the Internet and mobile phone. Why children? As children become more exposed to new media through school and Home, it is important to investigate how they use and appropriate these technologies in their everyday life. Do these technologies allow for continuity or change in children’s experience of leisure, school, peer and family relationships? II. HYPOTHESIS No stated hypothesis in the study. III. RESEARCH METHOD III.a Research Design Since the objective is to identify, describe and explain children’s activities in the new media environment and how they use these technologies, a qualitative design was employed for the study. This approach allows us to probe further into the contextual realm of children’s engagements with and in the new media. III.b Instrument Data were gathered through a depth interview guide, which allowed respondents to narrate and explain their uses of the Internet and mobile phone as well as their relationships online. The following are the concepts investigated and the corresponding questions: a. Access and Usage of the Mobile Phone/Internet 1. How did you come to own one? Why? 2. How long have you been using a mobile phone? 3. How often do you use the phone? 4. Where do you have Internet access? Why? 5. How often do you use the Internet? Why? b. Uses and Contexts of the Mobile Phone 1. What do you do with your cell phone? Why? 2. What types of messages do you send? Why? IV. CONCLUSION Acknowledging the lack of empirical studies on children and new media, this study asked how a sample of Filipino children integrated new media into their everyday lives and in their relationships with peers and family members. It sought to understand the uses of the Internet and mobile phone in the context of home (family life), school, and leisure activities of children. A contextual approach to the use of new media looks at how these technologies are incorporated into everyday routines and acknowledges how values and social practices influence new media uses. By comparing Internet and mobile phone uses, this preliminary study sought to ascertain the  meanings of these two different but related media among Filipino children. Data suggested that the contexts of family, school, and leisure defined the uses of the new media. The Internet was used mainly for information seeking related to school and interests, relational maintenance (friends and relatives) and leisure. On the other hand, the mobile phone was used for coordinating day-to-day practicalities, relational maintenance among family members and peers, and was deployed by parents as a means to monitor their children’s whereabouts and activities. In turn participants construed the medium as an extension of parental presence. The study also probed into family and peer relationships of participants in the new media environment. The goal was to provide evidence that would support or contradict opinion regarding the potential of the medium as an environment where social relations are created or maintained. Findings suggested that the media were used primarily to maintain the participants’ existing social networks rather than creating new ones. Rarely was the medium used to create new relations. It is important to note that existing relational dynamics in the family largely influence interactions on the mobile phone. Although the phone provided accessibility, it was not a guarantee in improving relations between parents and children, and among siblings. IV. ANALYSIS The obvious change is the accessibility and convenience that these new media provide to facilitate information search and communication. The impact can be seen in the way children do research and regard reading books. As the study unveiled, participants tended to spend less time in the library and get their material instead online, where information is easily copied. The ways school children do research on the Internet could be investigated in future studies. This finding also suggests a need to emphasize critical media literacy among young people that would train them to be critical consumers and users of online information. Almost all of the Filipinos of today are well-oriented when it comes to latest gadgets and its uses, especially the adolescents who used this in almost all of the time. However, there is a big problem when it comes to the â€Å"proper† use of technology. Some Filipinos tend to be abusing the true  essence of technology. Some used it for cyber bullying and any sort of crime related to this. Accessibility does not necessarily alter existing social and cultural practices; for example, participants tended to communicate more within their network of relations. Indeed for this sample of children, Filipino family and peer relational dynamics still find their way in the new media environment. V. REFERENCES Bakardjieva, M. and Smith, R. (2001).

Free Essays on What Caused Wilson Change In Opinion To Enter WW1

There were many reasons for the United States involvement in the War, but Germany’s great desire for more power and global influence is the most evident. â€Å"Militarism was another cause of the war, it was similar to the arms race of today, because Britain had a great navy, Germany wanted a great navy too. Germany and France competed for larger armies. The more one nation built up its army and navy, the more other nations felt they had to do the same.† At the start of the war, President Wilson declared neutrality of the United States and most Americans opposed US involvement in the European war. Not only was the US culturally similar to Great Britain and France, but these two countries where our major trade partners. The US understood that if the Allies lost the war, it would have a tremendous effect on our economy. This is why America began to see Germany as the â€Å"enemy†. A declaration of war was partially brought about by the sinking of the Lusitania in May 1915 and later merchant ships such as the City of Memphis, Illinois and Vigilancia.

Breast implant essays

Breast implant essays Despite the risks involved during surgery and the side effects afterwards, breast implants are widely sought in developed countries. In fact, there were 87,704 surgeries in America alone in 1996. Why do women want big breasts at all and are they fully satisfied with the results? This essay attempts to explore these conundrums. Many women are obsessed with their appearance and opt for breast implants to look attractive to others especially guys. Although two-thirds of men surveyed in 1997 reported that they are happy with their partners breasts just the way they are, women seek perfection, which comes at a steep price surgery. Only 19 percent of men admit that they wished their partners breasts were bigger whereas 26 percent of women say they want super size mammary glands. Nearly twice as many women as men think that droopy breasts are the end of the world. Finally, some women chose surgery to escape from teasing and harassment they experienced because they were small breasted (As if big breasts will shut men up!). However, implants doesn't mean that men will go gaga over you or that you'll have Bo Derek boobs. In fact, your life could get more complicated. The chance of mishap is high: during surgery the patient risks hemorrhage and the abnormal clotting of blood which can cause strokes. Afterwards, the side effects aren't life threatening but they are distinctively unpleasant. Breast implants can harden and scar breast tissues; the condition is very painful and disfiguring. The silicone gel put in a harder silicon bag to create a natural effect may leak and cause chronic diseases including breast cancer and immune system disorders. If there is a leak, a woman's breast deflates (can you imagine how embarrassing that would be?) and usually requires immediate removal or replacement. Women who have breast implant surgery are deceiving themselves if they hope implants will s ...

Human Resources- Relationships in the workplace Research Paper

Human Resources- Relationships in the workplace - Research Paper Example Companies have been attempting to establish clear, well-understood policies to minimize the potential for danger – both for the employees and the organization. However the role of the HR in an organization remains controversial as far as dealing with workplace dating and relationships is concerned. Gautier has explored the reasons for workplace romance and found that theories of attraction play a vital role. Social psychology also points out a strong link between proximity, familiarity and attraction. Because of close and frequent interpersonal interaction they are prone to develop relationships. People with similar beliefs, attitudes, education and background are also more likely to be attracted to each other. They have similar traits and goals; share each other’s excitement and frustrations, and celebrations (Loftus, 1995). At the same time, organizational attitude, culture and beliefs play a role in how the companies conceptualize, tolerate and manage workplace romance. The role of HR in workplace relationships is debatable. When Wal-Mart terminated the services of two of its workers who were dating, it was found that the supervisor used an out-of-date policy manual to justify their termination (Losey, 1993). A survey revealed that more than 70 percent organizations permit and accept workplace dating as most were of the opinion that the organization has no right to interfere in the dating between coworkers (Losey, 1993). However, when dating involves an employee dating a boss, or the upper management or the manager dating a subordinate, it has been found to be unacceptable (Gautier, 2007). Only if a supervisor dates a subordinate, can the organizations interfere and this has become important because of some well-known sexual harassment court battles (Jenner, 1993). There have been instances when an employee had voluntary--but not

Tanunda winery Case Study Example | Topics and Well Written Essays - 1750 words

Tanunda winery - Case Study Example The alternatives available, recommendations, and action and implementation plan for Tanunda Winery. Introduction The Tanunda Winery, one of the leading mid-sized wineries in Australia, was located in the Barossa Valley of South Australia. A young Australian-trained winemaker, Colin MacIntosh had started it in 1976. The Tanunda Winery started producing a range of red and white wines that were speedily gaining acceptance in the marketplace by 1985. The company had established a solid reputation in Australia as a consistent manufacturer of high-quality premium table wines. The company was known for its marketing skills. The company had been successful in generating revenues domestically but did not succeed in the international markets due to lack of an export strategy. There existed an ample opportunity for the company to enter the international markets. Problem Statement The main area of concern was to find way into the International markets so that Tanunda Winery could sell their qual ity table wines and increase their volumes. It was difficult to find which markets to precisely target. In the given case, the marketing manager of Tanunda Winery had been given an assignment to evaluate the feasibility of launching a major export drive. Key Issues The Tanunda Winery was successful in Australia but did not achieve success in international markets. The reason being it is an Australian company producing quality table wines and people worldwide hardly know about Australia as a producer of wine. The senior management group decided in a strategic meeting held in early 2000 that a substantial growth opportunity existed in export markets and therefore George Steen, the marketing manager started preparing for a feasibility study for the next strategy meeting. On forecasts of a very positive environment in several export markets by the Australian wine industry report, George found it as an opportunity to enter foreign markets in a big way. The major concern of Bruce Clark, t he general manager, was about the ability of entering worldwide markets and making profits because of severe competition from the old-world countries such as Italy, Spain, and France who are experts at producing well-recognized wines with huge volumes and value-pricing. Their main concern was to catch up with which markets to sell large volumes of wine. The recognition could be done via the Olympic Games to be held in Sydney. The marketing efforts led to increase in profits but the rate of increase was declining as well as the average returns which is measured by profits as a percentage of sales. In the previous two years, Tanunda was a passive exporter that is it did not make much effort in drawing wine importers and did not have any export strategy. The domestic sales which also marginally and an unpredictable sales pattern in the bottled table wine market was also an area of concern for Tanunda Winery. Ageing population in Australia led to stability in the wine markets domestical ly. The stability in the Australian markets was also a concern which pushed them to expand their international markets. Rising mergers and acquisitions in the early 1990s was a growing concern or issue for the mid-sized companies. The small companies joined hands with bigger companies and therefore increase the bigger companies’ portfolio of products. It was becoming difficult for mid-sized companie

Furniture and Interiors Essay Example | Topics and Well Written Essays - 250 words

Furniture and Interiors - Essay Example Stickley's idea of good furniture was more on the utility side. His kind of furniture was created for everyday use and was quite durable as it was functional. Designer Frank Lloyd Wright an American architect, was in sharp contrast to Stickley because he had a more naturalistic approach combining the use of modern materials with landscape and waterfalls. Frank was credited to have beautifully designed the falling water house in 1936 in Pennsylvania, which stands as a milestone in American arts and craftsmanship. He ensured that there was perfect harmony both from the inside as well as the surrounding environment because he cared both for the human being as well as for nature. Both Stickley and Frank Lloyd believed that wood has to be admired in its most natural form instead of bending, molding them into different shapes. They believed that the dramatic woody patterns of its grains would be emphasized if cut in straight lines.

Response Paper Essay Example for Free

Response Paper Essay The authors main argument is that the underclass ideology which says that the black underclass is a worthless, unwise, indiscriminate reproductive source of   an unproductive poor class of America as against the   affluent white American society, is actually a â€Å"distraction from the fact that poor urban African Americans are the ones who cannot find jobs , cannot attend good schools and   have nowhere to live† (Williams 360) because the white counterpart citizens exploit their poverty for their own welfare and selfish gains through Government Authorities and Banks under the guise of Credit Cards, Equity and Mortgage loans and the Federal Reserve Board Regulations. The argument is aimed The Americans and the Research Bodies of the underclass ideology who make such false claims. The author’s audience is the American citizen, Government Authorities who support these ideologies and the Mass media who promote it to misguide the masses against the underclass of African Americans and other minority communities in USA. The argument of the author proves the relevance of the underclass ideology to the discipline of anthropology as it exposes how the black African American community has been a victim of mock welfare and plastic partners- namely the credit cards and Banks.   The debt and poverty image of such people is as much the result of their deprivation of basic facilities by the Government as also by the fact that their spending habits are governed by their social, cultural, interpersonal relationships and attitudes which is the subject of Anthropology.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Works Cited Sanjek, R.

The Metamorphosis of Johnny Tremain :: Tremain

The Metamorphosis of Johnny Tremain Johnny Tremain is like a butterfly; he went through a transformation. Johnny Tremain is a book by Esther Forbes about a crippled boy during the American Revolution and the events he endures. Johnny Tremain was a very dynamic character because people and events affected him. People change main characters in many books. Johnny Tremain is no exception. In Johnny's case it was the Lyte and the Lapham families. Both the Lapham family and the Lyte family probably did not mean to change Johnny, but they did. Johnny was orphaned after his mother died but was able to stay in the Lapham's house and to be an apprentice to Mr. Lapham, an elderly silver smith who educated Johnny in this art. He was always Mr. Lapham's favorite because Johnny was the finest apprentice out of the three that were there until Dove, one of the apprentices, passed Johnny a cracked crucible. Johnny's thumb then got grown into his palm when he healed. After the injury, Mr. Lapham and the whole family found Johnny useless and queer (because of his thumb). " `Don't touch me! Don't touch me with that dreadful hand!' Issanah squealed." After then Johnny grasped the fact that he went from the top to the bottom in a matter of days. It taught him that nothing is forever. Furthermore, M rs. Lapham a widowed mother of four, was probably the cruelest Lapham of all, after he got crippled. She told him that he was only good for picking rags. She also virtually shooed Johnny out of the house. This made Johnny go find a better life outside of the Lapham's shop. It also taught him to be independent. There is usually more than one family that changes a dynamic character like Johnny. The Lyte family also helped Johnny in his transformation. The Lyte's are Johnny's rich relatives that claim they are not related to Johnny. Johnny has a silver cup to prove his relation, but the Lytes still deny any relation to Johnny and claim that he stole the cup from them. When Johnny was first looking for a job, he thought he could go to the Lytes and ask for some money.

Educational Goals and Philosophy :: Teaching Careers Education Essays

Educational Goals and Philosophy When I first came to Concord, there was no doubt that teaching would be my major. I have always been so inspired by teachers and thought that they put a lot of effort into their work. I can remember the teachers that actually reached me and touched my heart. I'll never forget them or the experience. It is so amazing how many lives a teacher must touch. A teacher has the power to reach out and make learning a memorable experience for every child. My main goal is to be a kindergarten or special education teacher. I love working with young children that don't pick up on things as quickly as the others. I love to watch their eyes light up whenever I help them realize that they can do it, too. Throughout my years of teaching, I hope to be a friend to these children. I want their first year of school to be a memorable one. I'm hoping that they will enjoy being in my class. The children in my classroom that are behind will have me working my hardest to help them catch up. It is a known fact that when young children fall behind in the early years of school, they never catch back up with their peers. That breaks my heart. Every child deserves a fair chance. Each of these students have a variety of background knowledge. Some might not have any because their parents don't work with them. Others might have parents that work with them every night. A teacher has to consider these factors when assessing their ability. The ability and actual knowledge might not balance out. I want the nature of my students to be open-minded and willing to take a chance to learn new things. This involves trust. My students will have to trust me. Whenever I give assignments they don't quite understand, I want them to feel comfortable coming to me for help. I want them to know that no matter what the problem is, I will be there. I don't want to be so intimidating that they feel afraid to ask me for help. A teacher's job is to me a mentor, but also a friend.

Finders keepers my ethical dilemma Essay

Introduction My mother always told me I must learn to think for myself, question a situation and most importantly, I must learn to say ‘NO’, cause when the devil shows or makes you an unbelievable offer it’s harder than you think to say ‘NO’. Regardless of ethnicity, religion or culture when faced with a moral dilemma there is no telling how you would react or what your decision will be, even if you grew up as a devout Catholic like I did, and were expected to obey the Ten Commandments till the day you die or ‘burn for eternity in hell!’, or if you are lucky, spend part of eternity in purgatory atoning for you sins. Often we are placed in situations that test our ethical resolve. Lapses in ethics due to a dilemma can occur because of the simplest of issues like a need or fear. A dilemma is a situation requiring a choice between equally undesirable alternatives. An ethical dilemma can also be known as a moral dilemma or temptation. Moral temptations are viewed as â€Å"the right choice verses the wrong choice†. The right choice is not necessarily the easy choice. Any situation in which there are two choices to be made, neither of which resolves the situation in an ethically acceptable fashion nor provides a satisfactory outcome for the chooser adequately describes a dilemma. Ethical dilemmas assume that the chooser will abide by societal norms, such as codes of law or religious teachings, in order to make the choice ethically impossible. Knowing how to best resolve difficult moral and ethical dilemmas is never easy. Situation I Found Myself In Three years ago I left my job as a teacher to work in an employment agency to gain ipractical accounting experience. Not long after I started working the owner fired her sister and sister-in-law leaving me as the only member of staff. In December of that same year a pastor well known to my employer came into the office and placed an envelope on the chair next to where he sat down. He got up and left the envelope there. Firstly, I had no idea the envelope contained. So when I saw the envelope I thought it was empty and I was pretty annoyed that this man had left an empty envelope on the chair and didn’t have the courtesy to throw his rubbish in the bin!! So instead of taking the initiative to throw the envelope in the bin, I left it there. Yes I left it there on the chair. Secondly thing you should know is that my boss and I were not on the best terms. My boss obviously irritated that I made no attempt to throw the envelope in the bin asked me to do so. As I picked up the envelope I realized it was not empty, I looked inside only to become conscious that not only was it not empty, but it actually contained a large sum of money in one hundred dollar bills. In fact it contained thirty thousand dollars. Yes, THIRTY THOUSAND! My dilemma at that very moment was whether to confirm to my boss that envelope was empty throw it in the bin and take the money when she left the office or let her know the envelope contained a large sum of money and it is possibly belonged to the pastor. But what if it did not belong to the pastor? I would lose out on some much needed money and besides, if it did not belong to the pastor we may not be able to find out who it belonged to. And I believe in my heart of hearts if we did not find who it belonged to my boss would have claimed the money herself. Finding the rightful owner could have been a challenge, as a great deal of different people passed through the office on a daily basis, most of whom we did not know and the pastor was not the only one in the office at the time. I needed the money, Christmas was right around the corner and getting presents for the family that year was going to be a challenge as my salary was less than it was previously. Here I was faced with a way out, but what should I do? It will help, surely help and with a little left over for the future it couldn’t hurt! This predicament can be examined through the paradigm of right verse right or right verses wrong. A paradigm refers to the framework or pattern of thought we use to determine and perceive events surrounding us. It is considered as the lens we see our life through, helping us to interpret the world around us and determine how we interact with this world. Our paradigm is infused with prejudice, assumptions, expectations and beliefs from which our values ethics and rules flow. On one hand wrong argues ‘finders keepers’, how it could be wrong to keep something that may not make it to the right person any way. On the other hand right argues that keeping something that don’t belong to you without trying to genuinely find the rightful owner or taking an action that will deny the rightful owner the opportunity to recover their lost item is as good as stealing. It is against the law to take something that doesn’t belong to you and you can go to jail if caught and convicted. Regardless of religion or social strata, honesty, responsibility, fairness, respect and compassion are considered the five main values. You only need to fail in one; if you’re not honest you will still be considered unethical even if you’re fair, responsible, and deeply compassionate. Without realizing it our actions and response to ethical situations is guided by the principles of ethical decision making. According to Kidder there are three such principles. The first is called Ends-Based Thinking: doing whatever is needed to produce the greatest good for greatest number. The second is The Rule Based Thinking: which focuses on what we ought to do rather than what we think is best and or might work. Third is the Care– Based Thinking: which is chiefly based on the golden rule â€Å"do onto others as you will have them do unto you†. The use of these principles is to help you determine the correct course of action when faced with a dilemma, not provide an automatic solution to moral problems and issues. So here I am with thirty thousand dollars in my hand. I had no idea it was that much at the time and the only thing I can think is I started asking myself questions and turning over the answers in my mind. The first thing I asked is what are the benefits of keeping this money? Is it fair? What if the person trace back their steps what would I say? What if it is for something important? If I was in this same situation how will I feel? Will I want this person to do everything in his power to give me back my money? WHAT IF I GET CAUGHT? What then? Is this the person I want to become? And my answers at the time was ‘Screw religion yes it is fair, I found it fair and square’. I don’t have to worry about getting what I need done I have more than I need now. So what if he comes back it’s just not here and if I am really good, which I was and still am, I won’t get caught. But if I were in that situation I would be devastated and would want whoever found it to remember me and try to get it to me. But I also did not want to become that person who has to think twice about being honest. So when my boss passed by and asked is there anything in the paper I opted to do unto others as I will have them do unto me as the care base thinking commands. I turned to her and said ‘yes’ with a shocked expression on my face ‘it has money a lot of money. I think it belongs to the pastor’. The money was returned to the pastor; I was out an extra thirty thousand dollars and had a guilt free conscience. In the end when dealing with moral issues and dilemmas riddled with moral complications we must deliberate for ourselves, keeping a careful eye on both the facts and on the ethical considerations involved. No situation is just cut and dry. Having good intentions and intuition is not all. Living an ethical life, being a good person, requires a disciplined commitment to think and act in accordance with the fundamental principles of right and wrong.

hamilton and jefferson essays

hamilton and jefferson essays Jefferson and Secretary of the Treasury Alexander Hamilton resulted in the formation of the first political parties. The Federalists adopted Hamilton's philosophies; Jefferson helped bring together the Democratic-Republican party. The views and ideas of these two political parties are still seen everywhere in government today, both Hamilton and Jefferson had extremeley important insight on how the government should be ran. What was to be Jefferson's chief problem for many years soon became apparent. He and Secretary of the Treasury Alexander Hamilton were completely at odds in their thinking. Jefferson, with his faith in the rational mind and his optimistic view of popular government, placed his trust in the land and the people who farmed it. He believed that the purpose of government was to assure the freedom of its individual citizens. With his fear of tyranny, he distrusted centralization of power and favored instead the spread of power among the federal, state, and local levels of government. Thomas Jefferson said, A people having sovereign power should do for itself all it can do well, and what it cannot do well, it must do through its ministers. The people...need to be guided by a council or a senate. But in order for people to trust it, they must elect its members... The people are admirable for choosing those to whom they should entrust some part of their authority. Hamilton, on the other hand, distrusted popular rule. "The people!" he once exclaimed, "the people is a great beast!" Whereas Jefferson favored an economy based on agriculture that stressed individual freedom, Hamilton worked to promote commerce, industry, and a strong central government, under which, he believed, the economy would flourish. He believed that to preserve order and the alliance between business and government, the moneyed class and the wealthy aristocracy should hold all political power. Jefferson retorted, ...
